The highly polluting industries such as Power, Cement, Iron & Steel, Chlor-alkali, Pharmaceuticals, Fertilizers, Refineries, Pesticides, Distilleries, Sugar, Pulp & Paper, Textile, Tanneries, and other categories of industries emit particulate matter and other gaseous pollutant into atmosphere. These industries also release pollutants through effluent discharge. The SPCBs and PCCs have prescribed standards for various pollutants emitted/ discharged by the industries as notified under the Environment (Protection) Act,1986 with minimal inspection of industries at site.
What Kinds of Gases Can a CEM Monitor For?
While there are many different types of continuous emission monitoring systems, In recent years Online Emission Monitoring Technology has received attention and interest in context of providing accurate and continuous information on particulate matter/ gaseous emission from stacks. There are already commercially available systems for monitoring parameters such as PM, HCl, HF, NH3, SO2, CO, O2, CO2, NOx, VOC, etc;.
For any given process, limits have been imposed on the quantum of emissions that an industry is permitted to release to the atmosphere for a particular parameter/ pollutant therefore an industry must comply with the legislation.
What Features Should A Standard CEM System Have?
There are many different makes and models of continuous emission monitoring systems out there, but the following is a list of some of the features you should look for:
- Sensing Technology Electrochemical, NDIR, Laser, Opacity, etc
- Continuous measurements on 24X7 basis.
- Direct Measurement of pollutant concentration in ppm, mg/m3 or volume % as specified in standards.
- Tried and tested technology with proven reliability
- Scalable ranges available for each gas
- A Wide range of gas sensitivity
- Highly efficient automatic purge and drain system
- Isolated 4-20 mA analog output for individual gases
- Hi/Low gas, low flow, and other programmable events
- Monitor multiple gases at the same time
- Compliance with legislation
- It must have low operation and maintenance requirements with low chemical consumption and recurring cost of consumables and spares.
These are just a few of the many features that may come with a standard CEM system. Make sure that your business is protected by the most advanced system on the market and leave nothing to chance.
